I've setup a system call handler in unity connection that will act as an auto attendant and I've assigned the call handler extension 450. My issue is that no matter what I've tried I can not access the call handler from either dialing internally or externally.
The call flow to this call handler is:
PSTN ---> extension 200 (Call forward no answer 24 seconds) ---> 450 (call handler)
If I call extension 200 from extension 250 internally, once it forwards I get:
"Please enter your PIN followed by pound"
If I call from the PSTN I get:
"Cisco unity connection messaging system. From a touchtone telephone you can dial an extension at any time..."
The integration between CUCM and CUC is a SIP trunk
In CUCM I created a CTI Route point. I created a corresponding DN of 450 and set it to Call Forward all to voicemail. Didn't work.
I deleted the CTI route point and tried creating a route pattern of 450 and setting the calling number mask to 450. Didn't work.
I've tried setting up a direct routing rule and a forwarded routing rule. I think this is the solution, but I'm not sure of the settings.
